    Well you said you replaced the sending unit, do you were in there, did you install it correctly? Any broken clips, mounts? Was it in a bind at all?

    Did you replace the sending unit (the float in the tank that controls the fuel gauge) or the fuel pump? IF you replaced the pump, did you buy factory Dodge or use aftermarket? Some cheap aftermarket fuel pumps are really noisy. When I worked as a mechanic, depending on where we bought the pump, we would get comebacks with customers complaining about noisy pumps.

    The whole sending unit I used a Napa one this time. The other was a auto zone it only lasted an 1 year. Only bought them both cause they were in stock and both right before a snow storm. But should I worry about it being loud. An buy a oem from dodge
    And replace it soon

    It's been awhile (10 yrs) since I worked on cars for a living, but if my memory serves me correct, I believe that Napa was where we got the ones that led to all the comebacks for noise. Most were so loud (basically you couldn't drive without the radio on to drown out the noise) that they never stayed in the vehicle long enough for us to see how long they lasted because the customer basically wouldn't take their car back until it was replaced again with a quiet pump, :realmad: (don't blame them, I wouldn't have it in my car either, but unfortunately, a lot of my bosses decisions were based on profit as apposed to what was right.) :dizzy::dizzy:
